Updated and Projected Cosmic Microwave Background Bounds on WIMP Annihilation

Charlotte Myers, Dominic Agius, Daniele Gaggero +1

We derive updated Cosmic Microwave Background (CMB) constraints on annihilating dark matter, and present forecasts for upcoming CMB surveys. We show that the addition of recent tem…

Inflation without an Inflaton II: observational predictions

Marisol Traforetti, Mariam Abdelaziz, Daniele Bertacca +3

We present a complete computation of the scalar power spectrum in the \emph{inflation without inflaton} (IWI) framework, where the inflationary expansion is driven solely by a de~S…

Tests of General Relativity with Einstein Telescope

Andrea Begnoni, Walter Del Pozzo, Matteo Pegorin +2

Gravitational wave signals from compact binary coalescences provide powerful and reliable probes of General Relativity. To date, the LIGO-Virgo-KAGRA collaboration has provided str…

samsara: A Continuous-Time Markov Chain Monte Carlo Sampler for Trans-Dimensional Bayesian Analysis

Gabriele Astorino, Lorenzo Valbusa Dall'Armi, Riccardo Buscicchio +3

Bayesian inference requires determining the posterior distribution, a task that becomes particularly challenging when the dimension of the parameter space is large and unknown. Thi…

\texttt{GWBird}: a toolkit for the characterization of the Stochastic Gravitational Wave Background for Ground, Space, and Pulsar Timing Array detectors

Ilaria Caporali, Angelo Ricciardone

The detection of the Stochastic Gravitational Wave Background (SGWB) is one of the most challenging tasks for both current and next-generation detectors. Successfully distinguishin…

Quantum production of gravitational waves after inflation

Alina Mierna, Gabriele Perna, Sabino Matarrese +2

A variety of mechanisms in the early Universe lead to the generation of gravitational waves (GWs). We introduce here a novel source of GWs generated by vacuum fluctuations after in…

Detectability and Parameter Estimation for Einstein Telescope Configurations with GWJulia

Andrea Begnoni, Stefano Anselmi, Mauro Pieroni +2

Future gravitational-wave (GW) detectors are expected to detect tens of thousands of compact binary coalescences (CBC) per year, depending also on the final detectors layout. For t…

Likelihoods for Stochastic Gravitational Wave Background Data Analysis

Gabriele Franciolini, Mauro Pieroni, Angelo Ricciardone +1

We present a systematic study of likelihood functions used for Stochastic Gravitational Wave Background (SGWB) searches. By dividing the data into many short segments, one customar…

Non-Gaussianity of Tensor Induced Density Perturbations

Mariam Abdelaziz, Pritha Bari, Sabino Matarrese +1

We investigate the non-Gaussianity of second-order matter density perturbations induced by primordial gravitational waves (GWs). These tensor-induced scalar modes arise from local…

Reconstructing Primordial Curvature Perturbations via Scalar-Induced Gravitational Waves with LISA

Jonas El Gammal, Aya Ghaleb, Gabriele Franciolini +17

Many early universe scenarios predict an enhancement of scalar perturbations at scales currently unconstrained by cosmological probes. These perturbations source gravitational wave…
